' To aZZ whomz't may concern.-

Be it known that I, GEORGE H. ELLIS, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Spinning-Machines; and I do hereby declare the following to be'a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to spinning-machines, and more particularly to that type of such machines generally known as twine-spinners, by which cordage, binder-twine, and the like are produced. Machines of this type comprise, primarily, a bobbin-spindle for carrying a bobbin and a flier rotatable about said bobbinspindle for imparting the necessary twist or spin to the materialand for winding the finished cord or twine onto the bobbin, a suitable stop-motion for stopping the machine when the cord or twine breaks, and other adjuncts. Owing to the high'speed at which these machines must be operated, they have commonly been constructed to run the flier and bobbin-spindle by separate belts from two pulleys on a driving or counter shaft; but such manner of driving the flier and bobbin-spindleis objectionable for many reasons, among which maybe noted the slipping of the belts, resulting in irregular quality of the cord or twine produced,'thecost of repairs, and so on. Moreover, in these high-speed machines unless the stop-motion devices are prompt to act efi'ectively in bringing the parts to rest upon the breaking of the cord or twine being spun the flier and bobbin spindle will make a number of revolutions to the injury of the cord or twine already wound on the bobbin. 7

It is among the objects ofmy present invention to overcome the objections above pointed out and to provide means whereby cord or twine of uniform and standard quality may be produced, and in the event ofbreaking the same the machine may be promptly brought to rest.

With these Objects in view my invention consists of the parts and combinations, as will be hereinafter more fully'described, and definitely pointed out in the claims.

-In the drawings, Figure l is a side elevation of a spinning-machine embodying my invention, parts being broken away. Fig. 2 is- Fig. 3 is an enlarged a plan view thereof. detail, partly in section, showing the means for driving the flier and bobbin-spindle, the feeding or traverse mechanism, and other details to be described. Fig. t is an end View of the machine looking from the right in Fig. 3, parts being broken away. Fig. 5 is a crosssection of the machine on the line 0000 of Fig. 2, and Fig. 6is a cross-section of the machine on the line y y of Fig. '2.

. Referring to the drawings, A represents theframe of the machine forsupporting the working parts and which may be of any usual or desired construction. To one end of the frame A is securely connected the gill or drawin frame A as at A u on which are mounted the shafts a a, carrying any usual orpreferred character of gill or drawing chains afldri'ven from the main driving-shaft A as will hereinafter appear.

Mounted on suitable supporting-standards are the usual feed-rolls a a, driven from the shaft a by means of the belt a passing over the pulley a on the end of s'haftg and the pulley a on one of the feed-rolls, as will be clear from Figs. 1 and 2, by which means material is fed to gillor driving chains a -to be drawn and delivered to the spinning devices, as usual.

Journaled in suitable brackets A, secured to the supporting-frame A, is the main driving-shaft A carrying the fast and loose pulleys A and A and driven from any suitable 0r convenient source of power, as by the belt A Mounted so as to rotate in any usual or desired'form of bearing B B supportedon the frame A, is the counter-shaft B, driven from the main driving-shaft A as by the bevel-1 pinions B B secured, respectively, to said -main driving and counter. shafts. The gill or driving chains a are preferably driven from the counter-shaft B through gearing connections comprisingjthe wornib, secured to the shaft, the worm-wheel b on theshaft b carried on the adj ustable arm I), changewheel-b intermediate wheel b and drivewheel I).

Journaled in bearings C 0, carried. by the main frame, is the flier-sleeve or' hollow shaft C, to which is secured the flier, comprising the heads C C, connected by the arms 0, on one of which is mounted the guide 0 for laying the cord or twine onto the bobbin. Secured to the flier-sleeve or hollow shaft C is the gear D, Fig. 3, which meshes with a gear D, mounted on the counter-shaft B and by which the said gear D and its connected flier are driven positively from the counter-shaft. Sliding freely within the fliersleeve or hollow shaft 0 is the bobbin-sleeve E, on which is mounted to rotate therewith the gear E, the latter having a grooved hub e, engaged by a projection e on the frame, whereby the said gear E may rotate with and yet permit the bobbin-sleeve E free lengthwise sliding motion therethrough by means and for a purpose to be hereinafter described. The gear E meshes with a flanged gear E loosely mounted on the counter-shaft B and having driving connection with said shaft through a friction-clutch comprising, preferably, a flanged disk E the flanges e of which run within the flange of the gear E and between it and friction-lugs, the latter comprising in one form of construction the pins e carrying friction-shoes 6 which bear upon theinnersurface of the flange of disk E The relations and size of the gearing just described are such that the flier for imparting the twist or spin to the cord or twine is positively driven at a high rate of speed, while the bobbin, which is suitably connected to the bobbin-sleeve, as usual in this class of devices, through the disk F, has imparted to it a much slower motion, the result of which construction is that while the flier and bobbin F' revolve in the same direction by positive gearing connection with the countershaft the flier continually passes the bobbin in their simultaneous revolutions, thereby winding upon the bobbin the cord or twine that has been formed. Since the coil on the bobbin continually increases in size as layer after layer is laid thereon, it follows that the difference in the relative speeds of revolution between the bobbin and flier must vary, and this issecured by the friction-clutch connection between the positive gearing for rotating the bobbin and the counter-shaft, such friction-clutch permitting the flier to drag the bobbin more or less during the process of building up, so that the cord or twine is laid with uniform tension throughout. As the cord or twine is laid upon the bobbin it becomes necessary to lay the coils in spirals to prevent overriding, and this I accomplish by giving to the bobbin a traverse motion within the flier by the following mechanism:

Suitably journaled in the main frame atff is a double screwf, driven from the countershaft B through the worm f on said shaft, which meshes with a worm-wheelf rotatably mounted on a studf and carrying abevelpinion f, which meshes with a corresponding bevel-pinion f on the end of the double screw. Projecting from the bobbin-sleeve E is a cross-head f movable back and forth between suitable guideways f on the supporting-frame, and said cross-head carries a suitable shoe f pivotally mounted therein and which travels in the threads of the double screw, as will be obvious. Thus as the double screw is rotated constantly in one direction the bobbin-sleeve E is caused to move lengthwise back and forth, carrying the bobbin with it, to thereby lay the cord or twine in regular spirals on the bobbin.

In order to provide an effective stop-motion to arrest the movements of the parts on the breaking of the cord or twine, I provide the stop-rod G,which carries a belt shipper or fork g to ship the belt from the fast pulley A to the loose pulley A when said rod is permitted to turn in its bearings g g under the influence of a suitable weight or weights g 1 and I utilize the turning movement of said rod to efiect the application of brakes, as will presently appear.

Mounted on the main frameadjacent the gears D and E are the supplemental supports g 9 in which the stop-rod G is adapted to turn and having a suitable hinge or pivotal connection with the frame in position to engage and bear against the teeth of one of the gears on the counter-shaft, as gear E is a brakeshoe H, pivoted at h and normally tending toward the gear E under the tension of a spring 7L2, one end of which engages the free end h of the shoe, and the other end is connected, preferably, to the supplemental support Secured to the stop-rod G is a projection or toe h", which when the said rod is turned to throw the belt onto the fast pulley engages the brake-shoe near its free end and depresses the same from engagement with the gear and against the action of spring 71 but when the rod G is turned to throw the belt onto the loose pulley the toe releases the brake-shoe to the action of the spring, thereby applying the brake.

It will be noticed that the gears D D and E E are given broad faces and that the teeth are in the form of helices or spirals, the result of which is that the strain or sudden pressure on the teeth incidental to high speeds is materially lessened, the noise reduced to a minimum, and a broad bearing-face is provided for engagement by the brake-shoe. While in the present embodiment of the invention I have shown a brake-shoe applicable to the gear E it is to be understood that it might be applied to the other gear D without change, or a brake-shoe might be applied to both gears D and E but as such construction is obvious it is not necessary to more fully describe or show the same.

The stop-rod G during the operation of the machine is held in position with the belt upon the fast pulley by means of a trip-catch i, pivoted at i and having at its end a projection or lug i which engages a corresponding recess in the end of a holding-catch i fast on the stop-rod G. The trip-catch 2' has a rearwardly-projecting end adapted to be engaged ICO by the arm or lug is, secured to or formed as a part of a stop-lever K, pivoted at its lower end to the machine-frame and provided at its upper end with a notch or recess 7c, through which the cord or twine is adapted to pass as it is spun by the flier and drawn toward the spool by the usual capstan drawing devices k k common in this class of machines. The stop-lever K is Weighted, so that if free to move it would fall into the position shown to the right in Fig. 5; but during the operation of the machine the cord or twine passing through the notch 7t and through the central opening 10 of the flier maintains the said arm in the position shown to the left in said figure. Should the cord or twine break, however, the said stop-lever K being unsupported at its upper end will fall into the position to the right in Fig. 5, the arm or lug is thereon striking the inner end of the trip-catch 2', thereby freeing the holding-catch and permitting the stop-rod G to turn under the action of the weights g Pivotally mounted on the machine-frame at m in proximity to the flier and in position to engage one of the heads 0 of the flier is the flier brake-shoe M, having a depending portion m, which when the stop-rod G is turned to throw the belt onto the loose pulley, as hereinbefore explained, is adapted to be engaged and moved'against the rim of head 0 by the arm m secured to the said stoprod. Thus it will be seen not only that the turning of the stop-rod shifts the belt from the fast to the loose pulley, but simultaneously therewith applies a brake to the bobbin-spindle-operating gears and to the flier.

It will be noticed from Fig. 5 that the lug or projection 2' on the trip-catch 1' projects therefrom in position to be engaged by the hand-trip m pivoted at m to a bracket m depending from the machine-frame. Connected to the end of the trip m as at M is a rod wt, preferably carried above the work-- ing parts of the mechanism in position to be readily manipulated by the operator when it is desired to stop the machine by hand. By depressing the rod m the trip m is caused to strike the lug or projection 11 and free the stop-rod, as before explained.

In machines of this general type the spool is supported on a spindle or rod on which it is reciprocated to lay the finished twine or cord in regular spirals, and in order to place and remove the spool as desired it is necessary that such spindle or rod be endwise movable. In the present embodiment of my invention I provide means whereby when the machine is at rest the said spindle may be moved endwise to change the spools; but when the machine is in operation and prior to starting the said spindle must be locked against such movement, thereby overcoming liability of accident, owing to careless operations.

Loosely mounted in the bobbin-sleeve E and movable lengthwise thereof to release the spool when necessary is the bobbin spindle or red S, having its end extending into a bearing 8 near the driving-shaft end of the frame. The bearing 3 is provided with any usual form of guideways s, in which slides a safety-gate S, having a hook or other convenient lifting ineans 8?, by which it may be raised in the guideways s, a suitable stop 3 being provided to prevent lifting the said gate entirely from the guideways. The gate S when in its raised position, as shown to the left in Fig. 4, uncovers the bearing s,'so that the bobbin-spindle may be withdrawn endwise; but when said gate is lowered, as shown to the right in said Fig. 4, it covers the hearing and end of the bobbin-spindle and effectually prevents endwise movement of the latter. In order to insure that the gate shall be in its lowered position prior to starting the machine and to maintain it locked in that position during the operation of the machine, I secure to the gate the safety-arm R, bent in the form shown and provided with a shoulder rat its free end, and I provide the belt-shipper g with an engaging lip r, Fig. 1. The form and length of the safety-arm R-is such that its shouldered end stands opposite the fast pulley A Fig. 4, and when in lowered position the lip r on the belt-shipper is adapted to ride over the shoulder r on the arm as the belt is shipped from the loose pulley A to the fast pulley A and lock the said arm against being raised as long as the belt is on the fast pulley. Should, however, the gate be raised when movement is given the belt-shipper to throw the belt onto the fast pulley, the forked end of the shipper will contact with the end of the safety-arm and movement of the belt onto the fast pulley be prevented.

While I have shown the preferred form of positive driving connections between the bobbin-sleeve, the flier-sleeve, and the countershaft as a particular character of gears, it is to be understood that such specific formsmay be varied, as may also the details in the stopping mechanism, without departing from the spirit of my invention.
